With electrodes chronically implanted on the surface and in the depth of the cerebral cortex, field potentials were led from various cortical areas of the bilateral hemispheres of monkeys performing self-paced hand movements. In the hemisphere contralateral to the moving hand, surface negative-depth positive, slowly increasing premovement potentials were recorded in wider portions of the premotor cortex and in the forelimb areas of the motor and somatosensory cortices. In the ipsilateral hemisphere, the potentials of relatively large amplitudes were often obtained in the premotor cortex, whereas either small or no premovement potentials were recorded in the motor and somatosensory cortices.
通过将电极长期植入猴子大脑皮层表面和深部，在猴子进行自主手部运动时，从双侧半球的各个皮层区域引导场电位。在与运动手对侧的半球中，在运动前皮层的更广泛区域以及运动和体感皮层的前肢区域记录到表面为负、深部为正且缓慢增加的运动前电位。在同侧半球，运动前皮层中常可获得相对较大振幅的电位，而在运动和体感皮层中记录到的运动前电位要么较小，要么没有。
